Eastern Christians and Their Churchesby Fr. Steven Hawkes-Teeples, S.J., is a very fine and brief introduction taking the reader through the various liturgical traditions that constitute the Christian East. This is a must read. Fr. Hawkes-Teeples is a former professor at the Pontifical Oriental Institute (Rome) and the author of several works. While he is a Jesuit priest he also serves in a Byzantine Catholic parish in St. Louis, MO.
